Caitlin> The patches that Tom recently posted address the L2-L3 Caitlin> coordination. They ensure that the TCP/IP stack used by Caitlin> the RNIC is consistent in its L2-L3 configuration with Caitlin> the host stack. For example, it will route packets to the Caitlin> same destination IP address the same way as the host Caitlin> stack, use the same MAC addresses for first hops, etc. But the patches don't provide full L2 coordination. For example if I install a netfilter rule that discards packets from a particular source MAC (a completely, 100% L2 notion), the RNIC will still happily accept connections from that MAC, right? Caitlin> Those will be compicated give and takes. There is no Caitlin> reason to hold up the L2-L3 work because of it. If it Caitlin> were, then SDP/IB should have been deferred until Caitlin> complete consistency was achieved. Updating one step at a Caitlin> time makes more sense. SDP/IB is not in the upstream kernel. And I agree that there are many issues with respect to network stack integration to work out before SDP is suitable for merging. - R. _______________________________________________ openib-general mailing list openib-general@openib.org http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
